                          NOTES TO UNAUDITED CONDENSED
                              FINANCIAL STATEMENTS


NOTE 1 - Integration of Financial Statements Reported on Form S-4

The Unaudited Condensed Financial Statements should be read in conjunction with
Decora, Incorporated's (the "Company") Audited Financial Statements for the
fiscal year ended March 31, 1998 included in Amendment No. 1 to Form S-4
Registration Statement under the Securities Act of 1933 for Decora Industries,
Inc. (the "Parent") and the Company dated September 4, 1998. The Company, a
wholly-owned subsidiary of the Parent, is a leading manufacturer and marketer of
self-adhesive consumer decorative and surface coverings and other specialty
industrial products. The Company considers its operations to constitute a single
business segment.

In the opinion of the Company, the accompanying Unaudited Condensed Financial
Statements contain all adjustments, consisting only of normal recurring
accruals, necessary for a fair presentation of the results for the interim
periods.

Certain reclassifications of prior year amounts have been made to conform to the
current year presentation.


NOTE 2 - Acquisitions, Extraordinary Item and Acquisition Related One-time
Charge to Cost of Goods Sold

Acquisitions

On April 29, 1998, the Company acquired certain assets, which had constituted
Rubbermaid's Decorative Coverings Group (the "DCG"), for a purchase price of
approximately $62.5 million (the "Rubbermaid Acquisition"). The assets acquired
included inventory, certain manufacturing equipment, tradenames and all other
rights to three product lines: (i) the Con-Tact self-adhesive line, which is
manufactured by the Company, (ii) the Shelf Liner light-adhesive line, which was
manufactured by Rubbermaid, and (iii) the Grip Liner non-adhesive covering line,
which is manufactured by a third party pursuant to the terms of an exclusive
manufacturing agreement.

The acquisition cost for the DCG of approximately $64.6 million (purchase price
of $62.5 million, adjusted for acquisition related closing costs of
approximately $3.6 million, less amounts related to transition services of $1.5
million) was allocated to the assets acquired as follows:


<TABLE>
<S>                                                 <C>        
               Inventory                            $ 7,500,000
               Property and equipment                 1,000,000

               Intangible assets:
                  Con-Tact tradename                 20,300,000
                  Customer relationships             27,400,000
                  Goodwill                            8,400,000
</TABLE>



                                      -7-
<PAGE>   8

In order to finance the Rubbermaid Acquisition, the Parent issued senior secured
notes (the "Notes") which were fully and unconditionally guaranteed by the
Company. A portion of the Note proceeds was advanced to and used by the
Company for the Rubbermaid Acquisition (approximately $58,300,000) and to
refinance existing Company debt and related fees (approximately $29,023,000). At
the same time, the Company entered into a three year, $15.0 million secured
revolving line of credit (the "Credit Facility"). Its availability is based on a
factor of the amount of accounts receivable and inventory held by the Company.
As of September 30, 1998, the Credit Facility had not been utilized.

Direct financing transaction costs incurred of approximately $152,000 were
deferred and are being amortized, using the effective interest rate method, over
the term of the credit facility.


Extraordinary Item

As noted above, in conjunction with the Rubbermaid Acquisition, the Company
repaid existing debt, including an $18.0 million subordinated loan bearing a
coupon of 13%. As a result of the repayment of the subordinated loan and other
debt, the Company paid a one-time prepayment penalty of approximately $2.2
million and wrote off unamortized deferred loan costs of approximately $1.1
million. Consequently, an extraordinary charge of approximately $2.0 million
(net of income taxes) was recorded in the six months ended September 30, 1998.


Acquisition Related One-time Charge to Cost of Goods Sold

The results for the six months ended September 30, 1998 were also impacted by a
one-time non-cash charge of approximately $797,000 for the step-up in basis of
certain DCG inventory acquired in the Rubbermaid Acquisition. This charge
related primarily to inventory sold by Decora to Rubbermaid prior to the
Rubbermaid Acquisition.

NOTE 4 - Related Party Transactions

The Company paid management fees to the Parent of approximately $250,000 and
$500,000 during the three and six months ended September 30, 1998, respectively,
and $200,000 and $400,000 during the three and six months ended September 30,
1997, respectively, which are included in selling, general and administrative
expenses on the statements of income. These fees relate to various operating and
management services, including centralized cash management.

The "due from affiliates" represents the net intercompany transactions between
the Company, the Parent and the Parent's German subsidiary. The net balance due
from/(due to) affiliates was approximately ($82,993,000) and $18,227,000 at
September 30, 1998 and March 31, 1998, respectively. The Parent's sources of
income are limited to the management fees received from the Company, the
dividends, if any, that it receives from its foreign subsidiaries and
intercompany loans.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS


THREE MONTHS ENDED SEPTEMBER 30, 1998 VS. THREE MONTHS ENDED SEPTEMBER 30, 1997.

The Company's Condensed Financial Statements for the three months ended
September 30, 1998 include the operations arising from the April 29, 1998
Rubbermaid Acquisition. Net sales for the three months ended September 30, 1998
were $21,784 as compared with net sales of $10,308 for the three months ended
September 30, 1997. The increase of $11,476 resulted principally from the
Rubbermaid Acquisition.

Gross profit was $9,128 for the three months ended September 30, 1998 as
compared with $2,410 for the three months ended September 30, 1997. The increase
of $6,718 reflects the impact of the Rubbermaid Acquisition and the fact that
the Company now sells directly to retailers.

Selling, general and administrative expenses were $4,050 for the three months
ended September 30, 1998 as compared with $1,281 in the three months ended
September 30, 1997. The increase of $2,769 was a result of the change from being
primarily a contract manufacturer to being a vertically integrated manufacturer
and marketer of Con-Tact products following the Rubbermaid Acquisition.

Interest expense (income) was ($281) for the three months ended September 30,
1998 as compared with $361 in the prior year quarter. The decrease of $642 is
principally due to advances received from the Parent which repaid existing debt,
with the balance being invested in interest bearing accounts.

The Company recognized income before income taxes and extraordinary item of
$5,359 in the three months ended September 30, 1998, as compared with $96 in the
three months ended September 30, 1997. This increase is principally a result of
the increase in earnings resulting from the Rubbermaid Acquisition. The results
in the prior year were also impacted by $672 of non-recurring charges.

Net income of $3,216 for the three months ended September 30, 1998 was $3,158
higher than the three months ended September 30, 1997 of $58 as a result of the
above-noted changes and a $2,105 increase in the provision for income taxes.

SIX MONTHS ENDED SEPTEMBER 30, 1998 VS. SIX MONTHS ENDED SEPTEMBER 30, 1997.

The Company's Condensed Financial Statements for the six months ended September
30, 1998 include the operations arising from the Rubbermaid Acquisition. Net
sales for the six months ended September 30, 1998 were $39,279 (reflecting the
Rubbermaid Acquisition since April 29, 1998) as compared with net sales of
$19,455 for the six months ended September 30, 1997 (which do not reflect the
Rubbermaid Acquisition). The increase of $19,824 resulted principally from the
Rubbermaid Acquisition.

Gross profit was $14,829 for the six months ended September 30, 1998 as compared
with $5,001 for the six months ended September 30, 1997. The increase of $9,828
reflects the impact of the Rubbermaid Acquisition and the fact that the Company
now sells directly to retailers. The 



                                      -10-
<PAGE>   11

increase in gross profit for the six months ended September 30, 1998 was
partially offset by a one-time non-cash charge of $797 for the step-up in basis
of DCG inventory acquired in the Rubbermaid Acquisition. Excluding the impact of
this one-time charge, total Company gross profit would have been $15,626.

Selling, general and administrative expenses were $6,065 for the six months
ended September 30, 1998 as compared with $2,704 in the six months ended
September 30, 1997. The increase of $3,361 was a result of the incremental sales
and marketing costs incurred relative to the change from being primarily a
contract manufacturer to being a vertically integrated manufacturer and marketer
of Con-Tact products following the Rubbermaid Acquisition.

Interest expense, net was $68 for the six months ended September 30, 1998 as
compared with $715 in the prior year. The decrease of $647 is principally due to
advances received from the Parent which repaid existing debt and which were
invested in interest bearing accounts.

The Company recognized income before income taxes and extraordinary item of
$8,696 in the six months ended September 30, 1998, as compared with income of
$910 in the six months ended September 30, 1997. This increase is principally a
result of the increase in earnings resulting from the Rubbermaid Acquisition.

Net income of $3,199 for the six months ended September 30, 1998 was $2,653
higher than the six months ended September 30, 1997 as a result of the
above-noted changes, an extraordinary charge of $2,019 in the current year
period and a $3,144 increase in the provision for income taxes.

Year 2000. Many existing computer systems, communication systems, machines and
other items, whether large or small, which utilize microprocessors and/or
software use only two digits rather than four digits to process date-related
transactions. As a result, many of these items will not be able to correctly
process a transaction with the year 2000 date, as the "00" could cause the
program or system to fail or create erroneous results before, on or after
January 1, 2000 (the "Year 2000 Issue"). The Company has employees who have the
task of identifying potential Year 2000 Issues and overseeing the implementation
of solutions with respect to these issues where possible.

The Company recently completed Phase I of a program to replace its primary
management information and communication systems with full Year 2000 compliance.
This included hardware and software required to operate its telephone systems
and its accounting systems (including general ledger, accounts receivable,
accounts payable). Phase II of this program, which is scheduled to be completed
in February 1999, will also convert manufacturing control systems to Year 2000
compliant systems. The combined hardware and software costs of Phases I & II are
estimated to be approximately $600,000.

In addition to its primary management information system, the Company utilizes
personal computers, which function either on a stand-alone basis or as
workstations on an integrated network. These computers utilize a variety of
operating systems and software packages ranging from Windows NT to DOS
platforms. The Company believes that the majority of these systems can and will
be made Year 2000 compliant prior to January 1, 2000 at little or no cost to the
Company through software updates provided by the respective software vendors.
Any full system replacements, which may be required, are not anticipated to have
a material impact on the cash flow of the Company and can be funded from
operating cash flow. The Company is in 



                                      -11-
<PAGE>   12

the process of reviewing other equipment and systems including, but not limited
to, fax machines, cellular telephones, security and other systems in order to
determine and remedy any potential Year 2000 Issues. The Company does not
separately track the incremental costs incurred for the investigation, analysis
and remedy of Year 2000 Issues. Such costs consist principally of related
payroll costs of certain members of its systems and operations groups.

The Company sells its products primarily to retailers, distributors and original
equipment manufacturers with a significant number of such transactions occurring
electronically. The Company also purchases raw materials from many vendors;
however, the majority of such purchasing transactions are not handled
electronically. If the Company, or any third party with whom the Company does
business, were to have a Year 2000 problem, the Company's business could be
seriously disrupted which could negatively affect the financial condition and
results of operations of the Company. This is particularly true in the case of
retail customers where high volume transactions would have to be converted to a
manual system until any Year 2000 Issue was resolved. The Company is in the
process of reviewing the Year 2000 compliance status with its vendors and
customers and to-date has not become aware of a situation which would have a
material adverse impact on the Company's operations and/or financial condition,
although no assurances can be given that such a problem does not exist, or will
not exist in the future. As the Company continues to evaluate the Year 2000
compliance status of its suppliers and vendors, it will also develop contingency
plans to deal with any potential problems that may arise in this analysis.
